Troubleshooting Network Interfaces on EX3200 and EX4200 Switches
This topic provides troubleshooting information for specific problems related to interfaces
on EX3200 and EX4200 switches.
•
The interface on one of the last four built-in network ports in an EX3200 switch (for
example, interface ge-0/0/23) is down on page 1175
•
The interface on the port in which an SFP or SFP+ transceiver is installed in an SFP+
uplink module is down on page 1176
The interface on one of the last four built-in network ports in an EX3200 switch (for example,
interface ge-0/0/23) is down
Problem
The interface on one of the last four built-in ports (
ge-0/0/20
through
ge-0/0/23
on
24-port models or
ge-0/0/44
through
ge-0/0/47
on 48-port models) of an EX3200
switch is down.
An SFP or SFP+ uplink module is installed in the switch and a transceiver is installed in
one of the ports on the uplink module.
When you check the status with the CLI command show interfaces ge- or with the J-Web
user interface, the disabled port is not listed.
Cause
The last four built-in ports use the same ASIC as the SFP uplink module. Therefore, if
you install a transceiver in an SFP or SFP+ uplink module installed in an EX3200 switch,
a corresponding base port from the last four built-in ports is disabled.
Solution
If you need to use the disabled built-in port, you must remove the transceiver from the
SFP or SFP+ uplink module. Alternatively, you can install an XFP uplink module instead
